摘要：
In this paper, we have investigated the classical tests of General Relativity like precession of perihelion, deflection of light and time delay by considering a phenomenological astrophysical object like Sun, as a neutral regular Hayward black hole in Rastall gravity. We have tabulated all our results for some appropriate values of the parameter sigma. We have compared our values with sigma = 0, which corresponds to the Schwarzschild case. Also the value of sigma = 0.7187 x 10(-4) is of particular interest as it gives some promising results.
